Abstract
The utility model relates to a refrigerant liquid recycling device in a low temperature gas-liquid separator in industry refrigeration, which comprises a gas-liquid separator, the upper part of which is provided with a gas outlet tube, the lower part of the gas-liquid separator is provided with a gas inlet tube, the bottom of the gas-liquid separator is provided with a sewage discharge tube, and the device is characterized in that the gas-liquid separator is equipped with a pressure transmitter and a liquid level sensor, and the side surface of the bottom of the gas-liquid separator is equipped with a heat gas bypass tube which extends into the bottom of the stored liquid in the separator. The device hash the beneficial effect that firstly, the heat gas discharged by a compressor is used for heating the liquid at the bottom of the separator, so as to enable the liquid to evaporate, compared with the structure of electric heating, heat exchange coil and the like, the device has simple equipment and excellent energy conservation property; secondly, the device is simple in structure and automatic control, and has high reliability; and thirdly, the device can rapidly recycle the liquid, and has small fluctuation effect on the refrigerating system.
Description
Technical field
The utility model relates to a kind of refrigerant liquid retracting device, specifically a kind of industrial refrigeration low temperature gas-liquid separator inner refrigerant liquid withdrawal system.
Background technology
In the industrial refrigeration system, gas-liquid separator is more common equipment.It can come out the drop separation of carrying in the refrigerant gas, prevents that effectively liquid from getting into compressor and causing Wet Compression even liquid hammer.When gas-liquid separator is used for gravity force liquid-supply, can also the flash gas that throttling produces be separated, avoid it to get into evaporimeter, effectively improve the heat transfer efficiency of heat transmission equipment.Yet in some pressure feed flow refrigeration system, gas-liquid separation and evaporimeter distance far or with evaporation equipment are installed on the same foundation face, and the interior liquid of separator this moment can't rely on gravity to get back in the evaporimeter.So effectively reclaiming these liquid all will be favourable to system's performance driving economy and stationarity.The recovery method of liquid is a lot of in the gas-liquid separator, for example electrical heating evaporation, heat exchange etc., but relatively poor, the complex equipments of its energy saving, and security and stability is relatively poor.For these reasons, liquid withdrawal system is very useful in a kind of gas-liquid separator that in the industrial refrigeration cryogenic refrigerating system, is easy to control automatically of invention.
Summary of the invention
The goal of the invention of the utility model is exactly with liquids recovery difficulty in the gas-liquid separator to existing industrial refrigeration; And recovery method control automatically is difficult for and the complicated defective of device structure; And design a kind of industrial refrigeration low temperature gas-liquid separator inner refrigerant liquid withdrawal system again, to guarantee security of system stable operation.
The technical scheme of the utility model is achieved in that it comprises gas-liquid separator; Escape pipe is equipped with on the top of gas-liquid separator; Air inlet pipe is equipped with in the bottom, and blow-off pipe is equipped with in the bottom, it is characterized in that: be equipped with pressure transmitter and liquid level sensor on the gas-liquid separator; The bottom sides of gas-liquid separator is equipped with the hot-gas bypass pipe, and the hot-gas bypass pipe stretches into the bottom of separator storaging liquid.Wherein on the hot-gas bypass pipe stop valve, magnetic valve and filter are housed.
The advantage of the utility model:
1, utilizes the hot gas heated separator bottom liquid of compressor air-discharging, make its evaporation, have equipment simple than structures such as electrical heating, heat exchange coils, good energy saving property;
2, apparatus structure and automatic control are simple, and reliability is high;
3, device liquids recovery speed is fast, and is less to the refrigeration system influence of fluctuations.
Description of drawings
Fig. 1 is the structural representation of the utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1; The utility model comprises gas-liquid separator 1, and escape pipe 7 is equipped with on the top of gas-liquid separator 1, and air inlet pipe 8 is equipped with in the bottom; Blow-off pipe 9 is equipped with in the bottom; Be equipped with pressure transmitter 2 and liquid level sensor 3 on the gas-liquid separator 1, the bottom sides of gas-liquid separator is equipped with the hot-gas bypass pipe, and the hot-gas bypass pipe stretches into the bottom of separator storaging liquid.Stop valve 4, magnetic valve 5 and filter 6 wherein are housed on the hot-gas bypass pipe.The utility model can utilize the hot gas heated separator bottom liquid of compressor air-discharging, makes its evaporation, realizes the recovery of liquid.
Principle explanation: when system gas liquid/gas separator 1 internal liquid is stored into certain altitude; And the interior pressure transmitter 2 of container this moment is lower than the controlling value requirement; Liquid level sensor 3 sends the signal of opening hot gas bypass solenoid valve, and the hot gas of compressor air-discharging enters into the separator bottom through stop valve 4, filter 6 and bypass solenoid valve 5; Carry out heat exchange through the sensible heat of hot gas and the liquid of separator bottom; Liquid is evaporated into saturated gas, and the overheated gas that compressor enters is cooled into saturated gas, and two strands of air-flows suck by the separator machine that is compressed.As time goes on, liquid is evaporated the lower limit until liquid level sensor control gradually, and liquid level sensor sends the signal of closing hot gas bypass solenoid valve, and the magnetic valve dead electricity is closed, and the liquids recovery process finishes.Be higher than the controlling value of pressure transmitter in the whole process like the pressure in the separator, hot gas bypass solenoid valve all must not.
